simple mail few question/bug

Hello, i have firefox aurora 9a2, and i have installed simple mail 2.81 beta4.

- i used simple mail few hours and i see that options: "Hide counter toolbar when there`s no mail" dosen`t do anything. i have all the time in my toolbar after mail icon number "0":/ if i think correctly with this option after icon i don`t will see any counter (numbers)?

- and when i configured options i see that sometimes i can`t go out from options with close button. i click close button but nothing happen (i must exit by click cross in the corner)

- mark as read options - when i enter 0 seconds mail dosen`t mark as read in real-time, so i figured out that 1 second is the shortest time? maybe you fix it when somebody like me enter 0 value

- i can translate few new options in polish language. what i must do? write email to author ? or write post on forum with new translated options?

1) you're right : with this option you should have no counter on the toolbar icon ... tested today on a fresh firefox Aurora install and it's work so i don't know ...
2) I guess this bug appears when you open the options page via add-ons: this will be fixed in the next version ...
3) this will be fixed in the next version ...
4) if you want to help me to translate Simple Mail, open an account on BabelZilla, search for Simple Mail and register yourself as translator for your language Thanx !
